HOLDER FOR ELECTRIC=AF C LAMPS.

SPECIFICATION forming part of Letters Patent No. 395,7 55, dated. January 8, 1889.

Application filed September 15, 1888. Serial No.285A45. (No model.)

To all whom it may concern.-

Be it known that I, J ACOB Piuvnowsiq, a 1 citizen of the United States, and a resident of 2 Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Holders for Electric- L Arc Lamps, of which the following is a speci i fication.

My invention is an improved holder and automatic cut-out for electric-arc lamps. lts object is to provide a convenient hanger for are lamps which, should any lamp of the series be dislodged from its position by a storm or by any accident, will of itself instantly and automatically close the circuit and prevent the other lamps in the circuit from being affected. By means of my invention I am also enabled to readily remove any lamp desired without disturbing the others.

The invention will first be described in connection with the accompanying drawings, and will then be particularly referred to and pointed out in the claims.

In the drawings I have indicated two forms of my holder, the principle being the same in each. It is evident that many other forms may be employed.

Figure 1 is a perspective view, in inverted position, of my preferred form of lamp-holder. Fig. 2 is a similar view of a modified form.

The board A, to which the metallic holders are attached, is preferably of wood, of any I convenient shape to be attached to a mast or other object. Upon this board are secured two metallic spring-holders similar in construetion, but attached with their holding ends pointing in opposite directions. Each holdingarm of one member crosses some portion of the opposite member, with which it is held in electrical connection by spring action when the lamp is lifted or thrown off, but which is held out of electrical connection by the sition.

In Fig. 1 each member of the holder is formed of a piece of spring-wire having a coil, B, intermediate the two ends. The springarm 17 upon one side of the coil terminates in a hook, 1), upon which one ring of the lamp is hung. The opposite end of the sire is formed into an eye, Z1 to receive the circuitwires 0. The portion of the holderhct ween the coil B and eye 0' has a double bond, forming the part b, which, when the two members of the holder are secured upon the board by v the staples d, crosses the plane of arm I), so that when the lamp (not shown) is disconnected the arm b of one member springs up and hears upon the cross portion I) of the opposite member, thus keeping the circuit closed, and this will result whether the lamp be dislodged from both hooks b or from only one of them. When the lamp is in position, the arms Z) of the holder are drawn down until stopped by the staples or keepers c, the current being then through the lamp.

The form shown in Fig. 2 differs from that shown in Fig. 1 in that the coil B is omitted and the opposite members of the holder have their arms Z) curved to cross and make contact with the poles I)". The tension of the curved spring-arms b in this figure, as in Fig. 1, holds them in contact with poles Z2 when the lamp is dislodged. So long as the lamp is in position the arms and poles are held out of contact.

The metallic holders are of course good conducting material, one being the positive and the other the negative pole of the lamp, as indicated by the signs I claim- I. A holder for electric-arc lamps, consisting of two lamp-supporting members of conducting material and forming, when the lamp is in operative position, its opposite poles, the

lamp-holding end of each member crossing the plane of the opposite member, the two members being held normally in electrical connection, but arranged to be disconnected by the weight of the lamp when in position and automatically returned to the normal position when the lamp is disconnected, substantially as shown and described.

2. The combination, substantiallyas specified, of the board A, the two metallic holders, 9

each consisting of a rigid part secured to the board and a spring holding-arm, the metallic holders being so formed that the spring-arm of each member crosses the rigid part of the op posite member, and the tension of the spring being to hold the opposite members in elecers B b b b 19 and staples (Z, for securing them trical connection, whereby the circuit is closed to the board, and the keeper e, to limit the through the lamp when in operative position movement of the armsb b.
